CRT Monitor Philips black screen when cold
Hallo!
My CRT monitor, Philips 109B, has black screen after 2 seconds when it is cold: the picture becomes bigger and fades away. If I turn it off and turn on, the picture again becomes bigger and fades out. When it is warm, after 20-30 minutes, if I turn it off and turn on, the screen appears and works very good. Could it be a cap? Thank you! S. |

Jamie If the picture is changing X and Y dimensions then an acceleration voltage is playing up, reducing magnitude leading to increasing dimensions but fading image |

Depends how much it costs to fix the CRT. If it's a bad cap, it might be obvious which one just by looking at it (bulging top and/or leaking), and the fix, excluding the OP's time, may cost a few dollars. The OP should of course make sure he's aware of the hazards associated with CRTs even when there's no power applied. Sylvia. |

OP's savings in electric bill ALONE justifies buying the new LCD, even if he can fix it for free. |

You can't even put a band-aid on it, because it's Teflon coated. |
